Children of immigrants can benefit from attending prekindergarten, though they enroll less, on average, than children with US-born parents. This detailed report draws on interviews conducted with over 40 prekindergarten directors and staff, directors of early childhood education programs, and other specialists to present strategies for improving prekindergarten enrollment among immigrant families and English Language Learners. This includes strategies for outreach to support prekindergarten enrollment; helping immigrant families overcome language, documentation, and other logistical barriers when enrolling their children in prekindergarten programs; and building trust and good relationships with immigrant parents and designing immigrant- and ELL-friendly programs.
